Frictionless pressure regulator



FRICT IONLESS PRESSURE REGULATOR Filed July 5, 1928 ATTO/ZNEY mally the valve 38 is suported a very small distance from the nozzle 39, and is supported in 43. The primary portion 42 `.has 4a forkedendso,

as to provide legs 44. The 'legs 44 extend on f The end of thesecondary portion `43 of kthe a toggle 41 is reduced in widthas :indicated Maids Islam asmrmuention: and extends into an adjuster 47. The. adjustm.

such a manner that the valve 38 may move toward or away from the nozzle 39 with but a minimum of resistance or opposition.

For the purpose of controlling the position of the valvel 38, I provide a mechanism which will The numeral 41 represents a toggle consisting i dorathe valve 38, thus insuring return of the valve of a primary portion 42 and a secondary portion opposite sides of the Valve 38 and :meende there 1,987,162 v the possibility of fluctuation n the pressure ded livered by the regulator.

The manner of supporting the valve 38, as I have previously pointed out, is a very important part of the invention. The chord 37 of the supporting means 35 is extremely flexible, and supports .the valve 38 in such a manner that only a minimum vof 'friction is oerd 'to thempuement of-f'thevalve 38 'in either direction and, furthermore, it provides an invariable straight line path 38.110 thesameposition of closure every time.`
